  From the article Standing desks and chaise longues are good options. Ball chairs, which bounce your spine into a C-shape, are not. I'm not sure if "ball chairs" are the same as you mean, but I guess they're.

    I've been sitting on a medicine ball for a while, and I agree that there's a big tendency to slouch into a C-shaped back. However, if you are conscious of your posture, it is possible to sit with an S-shaped back. At least, that's my subjective, anecdotal experience. A side effect of sitting with good S-shaped posture on a medicine ball is that I don't really "sit" any more. Instead, I straddle the ball as if I were riding a horse. However, for me the reason I switched to sitting on a medicine ball has nothing to do with back posture and everything to do with preventing a recurring pilonidal abscess.
